Product Description

The Air Lift 52440 4" Universal Air Spring Spacer is a suspension accessory engineered to support lifted trucks equipped with bellows-style air spring systems. When a vehicle's rear suspension is lifted by approximately 4" or more, standard air springs can over-extend and lose effective load support. These spacers install between the air spring and its lower mount bracket to add the required height and maintain proper operating geometry.

Constructed from high-strength steel with a spinal rib design for structural integrity, the 52440 spacers are compatible with many popular air springs, including LoadLifter and XL series components. By restoring correct air spring travel and preventing over-extension, this spacer set helps improve load-leveling capability, reduce squat under heavy loads, and maintain ride quality and suspension performance on lifted truck applications. Universal in design, fitment depends on matching with the appropriate air spring and mounting configuration.
